获取FaceBook上用户的信息

废话说多了没意思，直接一个代码就够了：

<html>
    <head>
        <meta http-equiv="content-type" content="text/html; charset=utf-8">
        <title>获取用户信息</title>
        <script type="text/javascript" src="lib/jquery/jquery-1.3.2.min.js">
        </script>
        <style>
            #get {
                background: green;
                width: 100px;
                height: 20px;
                margin: 0 0 0 0;
                color: white;
            }
        </style>
    </head>
    <body>
        <input id='get' value='GetUsersInform' type='button'/>
